Specification of Letters Patent.

Application filed November 6, 1907.

Patented Oct. 25, 19,10.

Serial No. 400,945.

To all whom it may concern:

' ject ot the King of England. and residentof T oronto, lfrovince, ofOntario, in the county of York and Dominion of Canada, have inventedcertain new and useful improvements in T vpe-VVriting Machines, olfWhich the following is a specification.

My invention relates to typewriting ma* chinos and more particularly toanti-friction nic-ans tor supportii'lg the type hars in place and the.object of said' invention is to provide simple and eiiicient means ofthe character speciiied.

To the above and other-ends Which-Will hereinafter appear, my inventionconsists in the features ot'.' construct-ion, arrangements of parts andcombinations of devices to he fully sel t'orih hereinafter andpartimllarly pointed out in the appended claims. A

Fig. l is an enlargedtransverse sectional vieu' of the same taken on the line 'jf-y of Fig. land lool'ring in the direction ot' the arroiv at said line. Fig. 3 .is adetail side view ot the hanger. Fig. i is an enlarged dot ail'fragnnntar'v transverse sectional view showing a portion ot thehearing. Fig. is a detail side view oi' the spacer friction balls androllers. Fig. 6 is a side view oi the adjustable cone piece. Fig. 7 isa. transverse sectional viewof the saine.

for the antil `'the pivotal center of the tyi l 8 a detail perspectivevien of one o'fl the hearing rollers.

he hanger or support comprises a stem or securing portion 1 from oneside of which projects a hearing piece ing "2 and a. cylindrical bearing3. Thoheariug'piece is apertured centrally for the reA ception of aheaded screw Ll, the enlarged portion 5 of which passes through acentral aperture G-ina companion hearing piece-.7 having a: cone thebearing and a lcylindrical bearing 9 corresponding to the-bearingi. Theconstruction is suehthat an adjustment ott-he screw. t effects anadjustment of the bearing piece 7 towardand away from the projectinghea-ring 'on the hanger axially of the type' bar.- :The type har 10 hasa bearing eye 1 1 split as indicated' at 12, and formed with having acone bearv bearing -S corresponding to ranged an extension 13 aperturedvto receive a screw 11i which takes at its threaded end in a tappedopening in the body of the type bar in order to effect an expansion andcontraction of the eye of the type bar so as to provide for anadjustment of the bearing in the' eye of the type bar toward and awaythe pivotal axis of the har. The eye of the type har is provided withoppositely' disposed eone hearings .15 and with cylindrical hearingwalls 16. Circularly arranged ant-iiiriction balls 17 and nen-sphericalor cylindrical bearing rollers 18 are arranged between the bearings onthe ha nger or support and the eye of the type har, the axis of thecylindrical rollers being parallel with the axis of revolution of thetype bar. These anti-friction balls and cylindrical rollers alternate asindicated in Fig. 1, the halls cooperating with the cone bearings 15, 2and 8 of the type har and hanger and the cylindrical aiutrfrictionrollers cooperating With the bearings 3, 9 and 16 of the hanger and typehar. The. bearings are preferably :1ras indicated in Fig. 1 so that theantilfriction halls contact with their bear'- ings at essentially thesame distance from e bar as the cylindrical rollers do with theirhearings. The relation ot' the parts is such that the type bar issupported primarily for turning movementon its bearings hy thecylindrical anti-friction rollers 184 but the length ot these. rollersis such that they do not receive a hearing contact at their ends and donot. therefore, take the lateral or axial thrust of the type har on itssupport, this axial thrust otf the-type har being taken bytheanti-friction halls 17. y

It will be understood that theJ screw 14 is provided to` effectarelative .adjustment of the bearings of the cylindrical ifeed rolle-rsin one direction or radially, Whereas the screw 4 is provided inorder'to effect a relative adjustment. between the cone bearingsfrom onthe hanger in order to effect an adjust-f justable bearing piece 7.`This spacer is apertured at-22 for cooperation with of the theauti-friction rollers 1'8 and is apertured at.

port therefor,

plane of: the type bar. The balls and rollers are preferably arranged asshown so as to be eut by the median plane of the type bar and thus avoidany cranking action.

li'hat lv claim as new and desire to secure by Letters Patent, ist-- l.'The combination of a type bar, a support therefor, a single set of"balls and a. single set of anti-friction rollers of aV diti'erent shapebetween said type bar and said support., the said sets of balls androllers together sustaining the weight of the type bar and the saidsingle set of balls alone receiving the axial thrust of the bar in bothdirections.

Q. The con'ibination of a. type bar, a support therefor, alternatingcircnlarly arand rollers of a different shape between said type bar andits support. (hoaxes of the rollers being parallel with the axis ofrevolution of the type bar, and independent; means for effecting arelative adjustment vbetween the bearings .tor said balls and rollers.

3. The combination of a type bar, a sup port therefor, alternatingcircularly arranged anti-friction balls and rollers of a different shapebetween said type bar and its support, the axes of the rollers beingparallel with the axis `type bar, means for effecting a relative adjustment for the rollers in one direction, and independent means foreffecting a vrelative adjustment between the bearings; for the balls inanother direction.
